@raven-worx said in QCompleter in QTableView: show always, even before user input:

declare the m_Editor variable as mutable.

This makes it compile (even though I'm not sure about the implications), but it doesn't help me: there is no Show event handled in editorEvent ever (tested with printf-debugging - yes, before the test for QLineEdit), I'm only getting Mouse events.

@SGaist said in QCompleter in QTableView: show always, even before user input:

Something like completer->popup()->show(); should do what you want.

Nope, does not help.

I figured (using qDebug, again), the place where I should put my popup-opening call is setEditorData. In there, I receive the QLineEdit and it's QCompleter: But I cannot make it show the popup. I tried now:

completer->setCompletionPrefix(index.data(Qt::EditRole).toString()); completer->complete(); completer->popup()->show();

Note: Sometimes the popup is shown for a very short time, but immediately hides. When repeatedly entering & leaving edit mode this only works the first time.

Hi and welcome to devnet,

The button you are seeking can be found clicking on the "Topic Tools" button :)

Hi and welcome to devnet,

I'd recommend bringing that matter to the Qt Creator team through the qt-creator mailing list(don't' forget to subscribed first) or #qt-creator IRC channel.
